Answer:
T₂ = 242 K
Explanation:
According to general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
Given data:
Initial volume = 125 mL
Initial pressure = 1.77 atm
Initial temperature = 213 °C (213 +273 = 486 K)
Final volume = 136 mL
Final pressure = 0.810 atm
Final temperature = ?
Solution:
P₁V₁/T₁ = P₂V₂/T₂
T₂ = P₂V₂T₁ / P₁V₁
T₂ = 0.810 atm × 136 mL × 486 K / 1.77 atm× 125 mL
T₂ = 53537.76 atm .mL. K / 221.25 atm . mL
T₂ = 242 K
Answer:
The correct option is: conjugate acid
Explanation:
Bases are the chemical substances that are proton acceptors and electron-pair donors. Therefore, when a base accepts a hydrogen proton from an acid it forms a conjugate acid.
Therefore, conjugate acids are formed when a base accepts a hydrogen proton from an acid. Also, if the base is a weak base then its conjugate acid is strong. Whereas, if the base is a strong base then the conjugate acid is weak.
